Water-soluble antioxidant derusting antirust liquid and preparation method thereof

Abstract

The invention discloses a water-soluble antioxidant derusting antirust liquid which is prepared from the following raw materials in parts by weight: 1-2 parts of 1H-benzotriazole, 1-2 parts of dodecenylsuccinic acid, 3-4 parts of sodium malate, 6-8 parts of flax oil, 2-3 parts of hydrochloric acid, 4-5 parts of polypropylene glycol acrylate, 1-2 parts of peregal O, 6-9 parts of sodium silicate, 1-2 parts of triglycidyl cyanurate, 1-2 parts of EDTA disodium, 4-5 parts of an auxiliary agent, and 300 parts of water. Through combined action of the high-molecular polymer monomers and the chelating agent, a thin film can be formed on a metal surface, thereby playing roles in isolating air, adhering an antirust agent and preventing oxidation; through use of sodium malate and the flax oil, the antirust liquid not only isolates the air, but also resists oxidation; through use of hydrochloric acid, the antirust liquid can rapidly remove rust; the antirust liquid is easy to clean up, and can immediately be removed by water washing; and the antirust liquid has few harmful substances, can prevent metals from discoloring, and is applicable to long and short term rust prevention of metal products and machinery parts.

Description

technical field [0001] The invention relates to the technical field of anti-rust, in particular to a water-soluble anti-oxidation, rust-removing and anti-rust liquid and a preparation method thereof. Background technique [0002] Rust prevention on metal surfaces is an important subject in industrial production. Traditional antirust liquids and antirust oils have both advantages and disadvantages. Ordinary anti-rust water contains a large amount of sodium nitrite, which is carcinogenic and is not conducive to environmental protection and human health. However, the use of humectants to prolong the life of anti-rust water brings the disadvantages of sticking hands and dust, and cannot prevent rust for a long time; Although the general dura-film anti-rust oil is suitable for long-term anti-rust, and the film is transparent and beautiful, there are few types of colorless and transparent resins, which are unstable and easy to oxidize and change color. They also need organic sol...

Problems solved by technology

Ordinary anti-rust water contains a large amount of sodium nitrite, which is carcinogenic and is not conducive to environmental protection and human health. However, the use of humectants to prolong the life of anti-rust water brings the disadvantages of sticking hands and dust, and cannot prevent rust for a long time; Although the general dura-film anti-rust oil is suitable for long-term anti-rust, and the film is transparent and beautiful, there are few types of colorless and transparent resins, which are unstable and easy to oxidize and change color. They also need organic solvents to dissolve, which brings the danger of flammability and explosion. It is not conducive to environmental protection and health; the general anti-rust oil uses mineral oil, which is difficult to degrade, and it will also cause the problem of difficult degreasing when used for short-term anti-rust
